Biochem/physiol Actions

Alosetron is a potent and highly selective antagonist of serotonin 5-HT3 receptors, nonselective cation channels found predominantly in the enteric nervous system of the gastrointestinal tract. These receptors are involved in the regulation of visceral pain, colonic transit and GI secretions that can contribute to the pathophysiology of irritable bowel syndrome (IBS). Alosetron is used clinically for treatment of women with severe diarrhea-predominant IBS.

Stimulated 5-hydroxytryptamine-3 (5-HT(3)) receptors promote intestinal motility, secretion, and sensation, effects that are related to the known pathophysiology of irritable bowel syndrome (IBS). A previous meta-analysis of 6 randomized controlled trials of the 5-HT(3)-receptor antagonist alosetron found that this agent
